Analogy: Grenade is to Gun as ____ is to ____. Choose the pair in which both belong to the same general category, paralleling “weapon : weapon”.

Introduction / Context:
The given pair lists two items from the same broad category (weapons). We must pick a pair that similarly belongs to one category.

Given Data / Assumptions:

• Grenade and gun are distinct weapons (same category).
• Seek a pair with parallel categorical sameness.

Concept / Approach:
“Man : Women” (read “woman” despite the legacy typo “women”) are both adult human genders—a same-category pair. Other options mix relations (siblings, parents) or a container–content relation (head : brain), which is not analogous to category pairing.

Step-by-Step Solution:
Identify category sameness in the stem (weapon : weapon).Select a parallel same-category pair among people: man : woman.

Verification / Alternative check:
Both members in each pair are co-level members of one class: weapons; adult humans.

Why Other Options Are Wrong:
Sister : brother and father : mother imply family-role opposites, not just co-membership; head : brain is part–whole.

Common Pitfalls:
Choosing a relation (kinship, part–whole) instead of pure category membership.

Final Answer:
Man : Women.
